Freelancer Type Website Needed (polished version of GAF)

I have posted and accepted a similar job to this - but am unsure if the person who i gave it to is going to be able to do it due to an emergency.

I need a site built similar to GAF (this site). It would need to have alot of the features of this site - posting jobs, bidding on jobs, affilliate program, RSS feeds, memberships, profile pages, categories, payment gateways - but would be used for a different industry.

If you can build it from the ground up - and not the expensive - great. If you have a template you can modify for less - even better. I havent found any one with an exact template to use yet.

Teh finished product I want must have a cleaner smoother look to it - If you have a background in creative or can make the site look fancier than GAF - great.

CSS or very clean table style templating is fine and being strong with design even better - Something with an classy, elegant, appealing Web 2.0 feel to it would be ideal but as long as it works the first version doesnt have to be perfect!

The site needs to be able to accept and process payments automatically and have the ability to put money into an escrow account.

The site needs to also have a better profile page - one where vendors can upload pictures and or videos.

Vendors (providers) and buyers will be able to sign up for different memberships

Buyers will be able to post (with refundable deposit - similar to GAF) and if they select a winning bid pay a fee based on the amount of the winning bid.

The site needs to have an admin section where things can be managed.

I would like to see sites that you have developed, and please have been reviewed on this site.

I will PM you a spec doc - but you should be able to build a site like [url removed, login to view] (this site) if you want this job.

Delivery must include 100% functional site with mysql db setup - test on your servers - then transfer to mine.
